The appearances of the phrase "in an embodiment" in various places in the specification are not necessarily referring to the same embodiment nor are separate or alternative embodiments mutually exclusive of other embodiments. It is expressly understood that the described embodiments are merely examples from a multitude of embodiments that are of the application. Numerous variations and modifications supporting equivalents can be effected without departing from the spirit and scope of the application as defined in the following claims.

[0033] In order to make the technical personnel in the field of the present application better understand the scheme of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings.

[0034] With reference to Figures 1-3 The embodiment of the present application shows an oil pipe control assembly, which comprises an adjustment knob 1, an oil tank 2 and an oil pipe 3,

[0035] The oil tank 2 has an oil storage space, the oil tank 2 is provided with an oil inlet 202 and an oil outlet 203, the adjustment knob 1 is connected with the oil inlet 202, and the oil pipe 3 is connected with the oil outlet 203;

[0036] The inner wall of the oil inlet 202 is provided with threads 2021,

[0037] The adjusting knob 1 comprises a knob cover 101 and an outer threaded component 102, the outer threaded component 102 comprises opposite first and second ends 1021 and 1022, the first end 1021 is connected with the knob cover 101, the second end 1022 is sleeved with a sealing ring 103, the second end 1022 is inserted into the oil inlet 203 and is connected with the oil inlet 203 through threads, the sealing ring 103 is attached to the inner wall of the oil inlet 202, and the knob cover 101 is sleeved on the outer wall of the oil inlet 202.

[0038] In this embodiment, the oil storage tank 2 is internally designed with an oil storage space for storing hydraulic oil required for brake or gear shifting and the like, and the hydraulic oil is filled in the oil storage space and the oil pipe 3. In a bicycle, the oil storage tank 2 can be a structural component with a closed internal cavity space in the existing structure of the bicycle, and can be a hollow bicycle handle, a hollow bicycle connecting pipe (such as a stem), etc.

[0039] The tank body of the oil storage tank 2 is provided with an oil inlet 202 and an oil outlet 203, and the number of the oil inlet 202 and the oil outlet 203 can be determined according to the specific use scene, which can be one or multiple. The outer threaded component 102 is inserted into the oil inlet 202, and rotating the adjusting knob 1 drives the outer threaded component 102 connected to the adjusting knob 1 to advance along the threads into the oil inlet 202 (the advancing direction is directed into the oil storage space) or retreat (the retreating direction is directed out of the oil storage space).
